General Characteristics Does have blood vessels variations in blood supply ligaments and tendons dont heal as fast because they are poorly vascularized Cartilage is avascular no blood supply heals very slowly ID: 681381

Connective Tissue
General Characteristics
Does have blood vessels-
variations in blood supply (ligaments and tendons don’t heal as fast because they are poorly vascularized)
Cartilage is avascular –no blood supply- heals very slowly
General FunctionsSlide3
Connective Tissue
General Characteristics
Does have blood vessels-
variations in blood supply (ligaments and tendons don’t heal as fast because they are poorly vascularized)
Cartilage is avascular –no blood supply- heals very slowly
2. Has extracellular matrix- a non-living substance outside the cells (surrounds cells), secreted by the connective tissue cells
General FunctionsSlide4

Can bind together other body tissues
Can absorb large amounts of water and serve as a reservoir (fibrocartilage between vertebrae)Slide9
ClassificationSlide10
Bone
Description
Osseous tissue
Bone cells are small caves called lacunae surrounded by hard matrix of calcium phosphate
Protects organsExamples
Skull, protects the brainSlide11
Cartilage
Description
Less hard and more flexible
Examples
Hyaline cartilage – glassy and smooth, found at the
ends of bonesFibrocartilage – cushions bones, intervertebral disksElastic cartilage – stretchy, in earsSlide12
Dense Connective Tissue
Description
Collagen fibers in a dense matrix
Cells, called fibroblasts, are more crowded
Examples
Ligaments and tendonsSlide13
Loose Connective Tissue
Description
Softer and fewer cells, more matrix
Examples
Cobwebby
covering over muscles – AreolarFat – Adipose tissueSlide14
Blood
Description
Cells within a liquid matrix called plasma
Examples
Blood
